The literature on International Diversification suggests that investors and analysts value foreign earnings differently than domestic earnings. Prior studies also show an overall "valuation discount" for firms with foreign operations. To my knowledge, no study has empirically tested and found there to be differences in earnings quality for these firms. This study investigates differences in the quality of earnings for U.S. firms with foreign operations using a direct measure (discretionary accruals) and an indirect measure (investor perception of earnings). I also consider the impact of audit quality on each measure of earnings quality. In the first part of my dissertation I find firms with foreign operations report lower discretionary accruals than firms with only domestic operations. This indicates that auditors, similar to investors and analysts, report more conservatively for firms with foreign operations. My results show that audit quality further reduces the absolute value of reported accruals, and I find a higher level of reported "income decreasing" accruals for these firms. In the second section of my dissertation I consider the impact of audit quality on investor perception of earnings. Similar to earlier papers I find that foreign earnings changes are more highly associated with changes in firm value than domestic earnings changes, and this larger earnings response is attributed to negative changes in foreign earnings. I also find that audit quality improves investor perception of foreign earnings for firms with foreign operations. While there are ample studies demonstrating that firms with foreign operations are valued differently than firms with purely domestic operations, my study is the first to provide empirical evidence about how audit quality impacts financial reporting, the quality of earnings, and investor perception of earnings for firms with foreign operations. / Business Administration/Accounting
